Software developer

I build calm,
considered web apps.

Hi, I'm Hayley — a software developer who likes shipping small, useful things.

I'm working through my own complicated health journey, and a lot of what I build comes from real needs — calm, private tools that make a messy thing feel manageable. I care about clear interfaces and useful software.

When I'm not coding I'm probably wrangling a herd of guinea pigs.

Relentless

Your health, untangled, for you.

A personal medical record for people juggling many medications, diagnoses, specialists, and procedures — and all the tangled connections between them. A calm, private place to make sense of your own care.

BAGGAGE

Sort out your baggage.

A little web app for organising the things you pack and carry. Built to adapt to whatever kind of trip you're taking.

Hayley's Herd

Management app for my guinea pigs.

An app for keeping tabs on my guinea pig herd — logging sightings, health, and family trees, plus PigCam, a live video feed of the enclosure. The app is just for me, but they pigs are Twitch for everyone!
